During the sale of our home, inspections recommended replacing a window with a broken locking mechanism. The window and its parts are no longer made, so I had to 3D print some replacements to avoid the large expense of replacing the whole window.

When Hoplite Industries needed some overpriced spacers, I was able to 3D print some suitable alternatives for a fraction of the cost using OpenJSCAD! Watch my talk at Big Sky Dev Con in which I talk about making real things using code.
